I gave my mom a set of OXO kitchen knives and peelers for Mother's Day. I got a dollar from her in return.
What? Yeah. I was confused too.
Till she told me that it was bad to send someone knives or handkerchiefs. Apparently it means you want to break off the relationship. But if you send them a dollar in return as if you were paying for it, then you're fine.
WHAT?
I don't get it. But you're not supposed to. It's superstition. It's irrational. So I just laughed it off and accepted her dollar. It was so funny getting one dollar in the mail from my mom. Maybe I'll give her a 50 cent handkerchief next time and make some profit. oh yeah! haha.
(p.s. she likes the knives and says it cuts really well. which was the whole point because she's been using the same dull knives for years and accidentally cutting herself because of it.)
